While trying to catch a flight out of New York City on Wednesday, Lena Dunham experienced a major delay — but that's not why she's pissed.

Trans people hear hate speech on a daily basis. As Dunham's tweets show, they can't even board a plane without being subjected to cruel commentary. 

What these flight attendants said is not OK. Companies should hold their employees to the highest standard and strive to eliminate hateful dialogue. 

Props to Dunham for speaking up.
